Financial Highlights

Second-Quarter 2023 Results2

  • Second-quarter GAAP sales were $3.2 billion, up 2% sequentially. Core sales were $3.5 billion, up 3% sequentially, driven by Display Technologies. GAAP and core sales were down year over year, reflecting continued lower demand in several markets.
  • Second-quarter GAAP EPS was $0.33, up 65% sequentially. Core EPS of $0.45 increased $0.04, or 10%, from the prior quarter. The difference between GAAP and core EPS stemmed primarily from restructuring charges and also from non-cash, mark-to-market adjustments associated with the company’s currency-hedging contracts and Japanese-yen-denominated debt. 
  • Core gross margin of 36.2% and core operating margin of 17.5% increased sequentially by 100 basis points and 200 basis points, respectively, reflecting pricing and productivity improvement actions. 
  • Second-quarter free cash flow improved from the first quarter to $310 million.

Business Segments

Corning manufactures products at 124 plants in 15 countries and operates in five reportable segments: Optical Communications, Display Technologies, Specialty Materials, Environmental Technologies and Life Sciences.

Optical Communications Segment

The company invented the world’s first low-loss optical fiber in 1970. Since that milestone, Corning has continued to pioneer optical fiber, cable and connectivity solutions. As global demand driven by video usage grows exponentially, telecommunications networks continue to migrate from copper to optical-based systems that can deliver the required cost-effective capacity. The company's experience puts it in a unique position to design and deliver optical solutions that reach every edge of the communications network.

The Optical Communications segment is divided into two main product groupings – carrier network and enterprise network. The carrier network group consists primarily of products and solutions for optical-based communications infrastructure for services such as video, data and voice communications. The enterprise network group consists primarily of optical-based communication networks sold to businesses, governments and individuals for their own use.

The Optical Communications segment represented 34% of Corning’s total segment net sales in 2022.

Display Technologies Segment

The Display Technologies segment manufactures glass substrates for flat panel displays, including liquid crystal displays (“LCDs”) and organic light-emitting diodes (“OLEDs”) that are used primarily in televisions, notebook computers, desktop monitors, tablets and handheld devices. This segment develops, manufactures and supplies high quality glass substrates using technology expertise and a proprietary fusion manufacturing process, which the company invented and is the cornerstone of its technology leadership in the display glass industry. The company's highly automated process yields glass substrates with a pristine surface and excellent thermal stability and dimensional uniformity – essential attributes in the production of large, high-performance display panels. The company's fusion process is scalable and the company believe it is the most cost-effective process for producing large size substrates.

The Display Technologies segment represented 22% of Corning’s total segment net sales in 2022.

Specialty Materials Segment

The Specialty Materials segment manufactures products that provide more than 150 material formulations for glass, glass ceramics and crystals, as well as precision metrology instruments and software to meet requirements for unique customer needs. Consequently, this segment operates in a wide variety of commercial and industrial markets including materials optimized for mobile consumer electronics, semiconductor equipment optics and consumables, aerospace and defense optics, radiation shielding products, sunglasses and telecommunications components.

The company's highly durable glass, known as Corning® Gorilla® Glass, is a chemically strengthened thin glass designed specifically to function as a cover, or back-enclosure glass, for mobile consumer electronic devices such as mobile phones, tablets, laptops and smartwatches. Elegant and lightweight, Corning® Gorilla® Glass is durable enough to resist many real-world events that commonly cause wear or scratch damage and glass failure, while providing optical clarity, touch sensitivity and RF transparency, thus enabling exciting new applications in technology and design. In 2022, Corning unveiled its newest glass innovation, Corning® Gorilla® Glass Victus® 2, which delivers improved cover glass drop performance on rough surfaces like concrete, while preserving the scratch resistance of Corning® Gorilla® Glass Victus®. Corning® Gorilla® Glass is manufactured in the United States (“U.S.”), South Korea and Taiwan.

The company invented the world’s first transparent, color-free glass-ceramic suitable for smartphone applications, which is featured as “Ceramic Shield” on the front cover of the latest iPhone models. The company partnered with Apple to develop and scale the manufacturing of Ceramic Shield, which offers unparalleled durability and toughness.

The company's semiconductor optics include high-performance optical materials including Corning® HPFS® Fused Silica and Corning® ULE® Ultra-Low Expansion Glass, optical-based metrology instruments and custom optical assemblies for applications in the global semiconductor industry. The company's semiconductor optics products are manufactured in New York.

The Specialty Materials segment represented 14% of Corning’s total segment net sales in 2022.

Environmental Technologies Segment

The Environmental Technologies segment manufactures ceramic substrates and filter products for emissions control in mobile applications around the world. In the early 1970s, the company developed an economical, high-performance cellular ceramic substrate that is now the standard for catalytic converters in vehicles worldwide. As global emissions control regulations tighten, Corning has continued to develop more effective and durable ceramic substrate and filter products for gasoline and diesel applications, most recently launching low-mass Corning® FLORA® substrates and Corning® DuraTrap® GC gasoline particulate filters. The company manufacture substrate and filter products in New York, Virginia, China and Germany. The company sell its ceramic substrate and filter products worldwide to catalyzers and manufacturers of emission control systems who then sell to automotive and diesel vehicle or engine manufacturers. Although most sales are made to the emission control systems manufacturers, the use of its substrates and filters is generally required by the specifications of the automotive and diesel vehicle or engine manufacturers.

The Environmental Technologies segment represented 11% of Corning’s total segment net sales in 2022.

Life Sciences Segment

As a leading developer, manufacturer and global supplier of laboratory products for over 105 years, the Life Sciences segment works with researchers and drug manufacturers seeking to drive innovation, increase efficiencies, reduce costs and compress timelines. Using unique expertise in the fields of materials science, polymer surface science, cell culture and cell biology, the segment provides innovative solutions that improve productivity and enable breakthrough research for traditional small molecule, or chemical, drugs, biologics, vaccines and emerging cell and gene therapies.
